The test used for food allergy testing (ELISA) was originally presented as a way to eliminate possibly contaminated blood from the donation pool. Fuckery at the Red Cross, etc. stopped that simple testing from happening (cost too much!)

Vaccines are relevant to food allergies AND profits, obv. However, pharmaceutical companies are pretty much immunized from being sued for vaccine INJURY due the National Childhood Vaccine Injury Act signed into law in 1986 by Ronald Reagan.
Merck is being sued for fraud re: efficacy. The current MO is the benefits outweigh the risks. MMR opens the way for another whistleblower, too, William Thompson. Which brings us to Vaxxed, Wakefield, Tribeca, etc.
